Hi all. I am busy writing a program, in Microsoft Visual Web Developer, and have a database was several tables. The one I am focusing on now is the ACCOUNT table. This table contains username, password and email column.
I want to compare a username entered into a textbox with the existing usernames in the ACCOUNT table, so that I can create a message saying that the entered user already exists.
I know how to do this in C# with if statements, but am really unsure with SQL, since not sure how to use it with SELECT.Thanks
